Hydrolipidic film: what is it?

The hydrolipidic film is a thin protective layer present on the surface of the skin , composed mainly of water and lipids . This natural emulsion plays an essential role in maintaining skin hydration and defending against external aggressions. A damaged hydrolipidic film can lead to dry, dehydrated, and irritated skin. Let's discover its importance, its composition, and how to effectively restore it.

Composition of the hydrolipidic film

The hydrolipidic film is made up of two main phases:

• Aqueous phase : Composed of sweat and water from the deeper layers of the skin. This phase is responsible for maintaining the skin's slightly acidic pH, helping to protect it against microorganisms.

• Lipid phase : Mainly made up of sebum secreted by the sebaceous glands , it contains fatty acids, ceramides , cholesterol and other lipids . This phase helps retain water and maintain the elasticity of the skin.

Why is the hydrolipidic film essential?

This film acts as a natural protective barrier :

• It prevents dehydration by limiting water evaporation.

• It prevents the penetration of harmful substances.

• It contributes to the balance of the skin microbiota by regulating the skin's pH.

When damaged, the skin becomes more vulnerable and may show signs of sensitivity, dryness and irritation.

How long does it take for the hydrolipidic film to rebuild?

The skin continually produces the hydrolipidic film , but its complete reconstitution after an alteration depends on various factors, including age, general health and skin care. The reconstitution of the hydrolipidic film can take several hours to a few days , depending on the aggressions suffered and the care given to the skin. Overly aggressive cleansing or the use of unsuitable products can delay this process.

Signs of a damaged hydrolipidic film

A damaged hydrolipidic film can manifest itself by:

• Dryness and dehydration of the skin.

• Feeling of tightness and itching.

• Redness and irritation.

• Appearance of skin imperfections such as eczema or blackheads.
